Many tutors have their own resources, but they can certainly make recommendations for purchase.
For ongoing courses, they work students’ coursework. The key to 1-on-1 tutoring is developing a personalized lesson plan. Each student’s situation is unique and requires an individualized curriculum.
Therefore, the type of materials used will differ from subject-to-subject and it is something that your tutor will thoroughly explain to you. Fret not, he's got you covered there and that won't be your worry.
